Abstract

In a disclosed Schmitt trigger, an input stage includes a first p-channel field effect transistor (PFET) and a second PFET, which are connected in series to a VDD rail, and a first n-channel field effect transistor (NFET) and a second NFET, which are connected in series between ground and the second PFET. An output stage includes additional FETs for hysteresis. The first PFET and first NFET are different from the other FETs and have a higher voltage rating. For example, the first PFET and first NFET can be buried oxide field effect transistors (BOXFETs) and the other FETs can be laterally diffused metal oxide semiconductor field effect transistors (LDMOSFETs)). Gates of the first PFET and first NFET are connected to an input node. Gates of the second PFET and NFET are connected to receive reference voltages to prevent safe operating area (SOA) violations and control trigger voltage levels.

Abstract

A radio frequency (RF) switch includes a transistor stack with different sections having different configurations for achieving different parasitic capacitances. Specifically, a first section is connected to an input terminal and a second section is connected between the first section and an output terminal. The second section has over-gate gaps for reduced source-to-drain capacitance, whereas the first section does not. Additionally, gate-to-source/drain contact spacing can be larger in the second section than in the first section, transistor layout length can be longer in the second section than in the first section and/or source and drain interconnect interdigitation can be less in the second section than in the first section. Optionally, sub-sections of the series-connected transistors within the first and/or second sections also have different configurations. Thus, numbers and sizes of compensation capacitors within the switch and overall chip area consumed by the switch are reduced while maintaining a high Pmax.

Abstract

Disclosed are embodiments of computer-aided design (CAD) methods and systems that employ one or more electronic design automation (EDA) tools to flag parasitic diodes within a layout or netlist (depending upon the embodiments). In one embodiment, information contained in process design kit (PDK) tables (e.g., a first table with layer-specific design rules for devices in a processing technology and a second table with descriptions of parasitic diodes in the processing technology) can be used to identify any parasitic diodes within a displayed portion of an IC design layout. Once identified, parasitic diodes can be flagged within the displayed portion of the layout to provide visual cues intended to draw a user's attention to the parasitic diodes during the design process to ensure that any unintended or unwanted parasitic diodes are either accounted for when predicting IC performance or removed from the design to avoid a negative impact on performance.

Abstract

Disclosed are a photonic integrated circuit (PIC) design system and method including optical signal propagation simulation with coupling awareness to account for transition loss due to a difference between at least one specific physical parameter (e.g., curvature radius, material composition, etc.) in optically coupled photonic devices. Coupling awareness can be achieved by including, within a bus of a netlist between the photonic devices, at least one pair of physical data pins: one associated with a specific physical parameter in the light emitting photonic device and the other associated with the specific physical parameter in the light receiving photonic device. Alternatively, coupling awareness can be achieved by running a utility to identify a parameter mismatch between the light emitting and receiving photonic devices, developing a custom coupling cell to account for the mismatch, and inserting the custom coupling cell into a design layout for the PIC.

Abstract

A temperature-adaptive gate driver for a GaN switch includes a gate-to-source voltage adjustment unit and a driver for outputting an on-state gate-to-source voltage to a gate terminal of the switch. The on-state gate-to-source voltage is adjusted based, in part, on temperature of the switch. The amount of adjustment of the on-state gate-to-source voltage with rise in temperature is based, in part, on high-temperature gate-bias reliability data of the switch and is chosen for a favorable trade-off between performance and life-time. The gate-to-source voltage adjustment unit includes a temperature sense element for sensing temperature of the switch and outputs to the driver an output signal based, in part, on temperature. The gate-to-source voltage adjustment unit includes a regulator for receiving a feedback signal based in part, on resistance of the temperature sense element, and for causing a value of the output signal to be responsive to a value of the feedback signal.

Abstract

A disclosed structure includes a power amplifier and circuitry for implementing a biasing scheme that enables high power operation. The power amplifier includes parallel transistor chains connected to input and output transformers. Each chain includes series-connected first, second, and third n-type field effect transistors (NFETs) having front and back gates. The output transformer receives a variable positive power supply voltage generated using average power tracking. Front and back gates of each third NFET receive a positive bias voltage greater than or equal to the variable positive power supply voltage and a negative bias voltage, respectively. By negative back biasing the third NFETs, threshold voltages thereof are raised so a high positive bias voltage can be applied to the front gates to increase power output without violating reliability specifications. Optionally, by making the negative bias voltage temperature dependent, voltages at source regions of the third NFETs are held constant.

Abstract

A disclosed non-volatile memory (NVM) structure is implemented in a fully depleted semiconductor-on-insulator technology processing platform and includes multiple NVM banks with NVM cells including transistors. NVM banks have well regions in a substrate. Transistors of NVM cells of each NVM bank are on an insulator layer above a corresponding well region for that bank. A bias control circuit causes well regions for NVM banks in a standby state to be biased with a reverse back biasing voltage and causes a well region for an NVM bank in an operational state to be biased with a forward back biasing voltage. The bias control circuit can initiate forward back biasing during a cache data retrieval process (before NVM bank access) to ensure that the corresponding well region of an NVM bank at issue is fully biased when, following the cache data retrieval process, access to the NVM bank is still required.

Abstract

A system and computerized method verify product custody along a product manufacturing chain. The method may include verifying a first machine-readable (MR) code for a product level N is valid by comparing the first MR code to a database of valid MR codes. Where the first MR code for the product level N is verified as valid, a second, valid MR code is generated for a next product level N+1 in the database of valid MR codes. In addition, the first MR code for the product level N in the database of valid MR codes is invalidated, so it cannot be used again. The second MR code is formed for use with the next product level N+1, e.g., by the downstream product manufacturer. Custody of product levels along a manufacturing chain can be verified and secured, avoiding bad actors from inserting and profiting from fake parts into the manufacturing chain.

Abstract

A static random access memory (SRAM) cell includes P-type and N-type transistors having secondary gates. A node connected to all secondary gates receives a write enable signal (WEN). A low WEN forward biases the P-type transistors and increases the toggle threshold voltage (Vtth) of the SRAM cell to avoid data switching during a read. A high WEN forward biases the N-type transistors and decreases Vtth during a write. The SRAM cell can be implemented using a fully depleted semiconductor-on-insulator technology, where the secondary gates include corresponding portions of a well region below. In this case, an array of SRAM cells can be above a single well region. Alternatively, the array can be sectioned into sub-arrays above different well regions and a decoder can output sub-array-specific WENs to the different well regions (e.g., with only one WEN being high at a given time to reduce capacitance).

Abstract

A circuit structure includes an enhancement mode transistor and a turn-off slew rate controller for automatically adding drain-source capacitance to the transistor when the transistor is transitioning to an off state. The added drain-source capacitance slows the turn-off slew rate (dV/dt_off) of the transistor without also increasing the turn-off energy loss (E_off).

Abstract

An integrated circuit includes a fin having a height and a width under a gate of a selected fin-type field effect transistor (FinFET) that is less than the height and width along a remainder of the fin including under gates and for source/drain regions of other FinFETs. The IC includes a first FinFET having a first gate over a fin having a first height and a first width under the first gate, and a second FinFET in the fin adjacent to the first FinFET. The second FinFET has a second gate over the fin, and the fin has, under the second gate only, a second height less than the first height and a second width less than the first width. The resulting reduced channel height and width for the second FinFET increases gate control and reduces gate leakage, which is beneficial for ultra-low current leakage (ULL) devices.
